Acetylacetone based composite heat stabilizer
InactiveCN101508636AImprove thermal stabilityPreparation of aldehyde/ketone chelatesAcetylacetoneMagnesium
The invention provides an acetylacetone-based composite thermal stabilizer which is a mixture obtained by mixing zinc acetylacetonate, calcium acetylacetonate or magnesium acetylacetonate and hydrotalcite pro rata. The composite thermal stabilizer is suitable for chloride-containing high polymer, such as polyvinyl chloride, chlorinated polyethylene, chlorinated polyvinyl chloride, copolymer of vinyl chloride-ethylene or copolymer of vinyl chloride-vinyl acetate, has better thermal stability, prolongs the thermal aging time of the chloride-containing high polymer, and overcomes the shortcomings of poor long-term performance of single stabilizer of zinc acetylacetonate, poor transparency of stabilizer of calcium acetylacetonate, and poor initial colorability of stabilizer of hydrotalcite. The composite thermal stabilizer has low cost, good initial colorability, excellent long-term performance and good transparency, and is an efficient composite thermal stabilizer.
